Brazilian priest allegedly taped having sex with teen

(CNN) -- A police investigation continued Thursday into a Catholic abuse scandal in Brazil, which erupted last week when a network aired a video that it said showed a priest having sex with a 19-year-old altar boy.

The report, aired by the SBT television network, identified the priest as 82-year-old Luiz Marques Barbosa.

Police in Alagoas state in northeastern Brazil said Thursday that they were investigating the allegations before the TV report surfaced.

In the video, a man said to be Monsignor Marques Barbosa realizes he's being videotaped and is heard on camera asking, "Who is it? Who's at the window? Who is it? Who's there?"

SBT said the videotape was secretly made by an unidentified 21-year-old man who alleges that he was abused by the same priest, who serves in Arapiraca in northeastern Brazil.

Brazil is home to the world's largest Catholic population, with about three-fourths of the nation's 140 million citizens calling themselves Catholic.

The investigation comes amid recent allegations of child abuse against priests in Ireland, Germany, Austria and the Netherlands.

In Chile, a man who used to teach at a Roman Catholic religious order's schools in Spain has been arrested on suspicion of sexually abusing children, police said Tuesday.

Jose Angel Arregui Erana was arrested in August in Chile, where he was teaching. He was held on suspicion of filming the abuse of boys and possessing images of sexually abused boys, a Chilean cybercrime unit police commander, Jaime Jara, told CNN partner network CNN+.

Jara said Tuesday that the suspected crime of possessing the illegal images occurred in Chile but that the alleged sexual abuse of the students and the filming or videotaping apparently occurred earlier in Spain.

Arregui, who is in his early 50s, was a physical education teacher in Spain and is accused of placing hidden cameras in gyms and bathrooms to film sexual abuse of the students, Jara told CNN+.

The suspect in the Spanish case does not appear to have been a priest but a layman teaching in schools run by a Catholic order.
